Carbonaceous PM is made up of black carbon, primary organic aerosol (POA) and, especially, secondary organic aerosol (SOA), which is known to contain harmful reactive oxygen species and can damage lung tissue.

They found that soluble iron in the earliest oceans quickly combined with oxygen to form rust — forming reactive oxygen molecules, which damage biological tissue and make the cyananobacteria grow more slowly and produce less oxygen.

This metabolic demand makes brain cells particularly vulnerable to damage from oxidative stress, in which reactive oxygen species (ROS), sometimes called free radicals, exert toxic effects on cellular components.

This fact makes vacuum UV light extremely useful for industrial applications from sterilizing medical devices to cleaning semiconductor substrates because when it strikes oxygen - containing molecules on a surface, it generates highly reactive oxygen radicals, which can completely destroy any microbes contaminating that surface.

I've been experimenting with T10 dextran coated iron oxide nanoparticles, obviously not the same as fullerenes, but still a very interesting tool, I've been testing if the coating is giving the particle antioxidant abilities because of it's the (basically) indigestable sugar chains (glucose) creating a high surface area which are largely made from hydroxyl groups, I hypothesised this act's as a «sink» for reactive oxygen species converting them to water.

Free radicals like reactive oxygen and nitrogen species (ROS, RNS) are molecules missing an electron, making them highly unstable and capable of destructive interactions with lipids, DNA, and proteins.
